22. Summary • two different formation epochs for early jetted and non-jetted AGN: jetted sources form first! • we do not see the “parents” of aligned jetted AGN:
 - CMB quenching of extended radio emission?
 - heavy nuclear obscuration (dark bubbles)? we are likely missing many high-z jetted sources! Padova, 7 April 2017
